The command "icons:cache" does not exist.
If I run the command through the artisan facade, I get that error
Artisan::call('icons:cache');
Artisan::call('icons:cache');

private function bootCommands(): void
{
if ($this->app->runningInConsole()) {
$this->commands([
Console\CacheCommand::class,
Console\ClearCommand::class,
]);
}
}
